2 Claims. 1

This invention relates to improvements in burner apparatus.

The principal objects of the invention are directed to the provision of a gas burner which is constructed and arranged for various uses and is characterized by novel means for reinforcing the burner against warping and maintaining the.

burner during operation at an efficient operating temperature.

Various novel features and advantages of the invention will be observed'from the following description thereof in the form at present preferred.

In the drawing:

Fig. l is a side elevational view of a burner embodying the novel features of the invention;

Fig. 2 is a left end elevational View of the burner as shown in Fig. 1;

Fig. 3 is a sectional view on the line 33 of Fig. 1;

Fig. 4 is an elevational view of one plate of the burner shown in Fig. 1;

Fig. 5 is a transverse sectional view through the longitudinal strut of the burner; and

Fig. 6 is a partial plan view of the strut of the burner.

Referring now to the drawing in detail, the invention will be fully described.

A burner tube is represented by 6 which extends from a support 8. The support 8 is hollow and is adapted for connection to a gas supply system and the tube is closed at its left hand end. Gas is emitted from the tube 6 through a series of ports 1 along its upper side which may be of any size desired and relatively arranged to suit various conditions. i

A strut I6 is provided which is arranged at its inner end for securement to the support 8 as shown in Fig. 1. 1 l l A strap i2 encircles the outer end of the tube 6 and has side parts M that lie on opposite sides of the strut. A screw l6 passing through the side parts and strut has a nut l8 thereon to draw and hold the parts together.

A plurality of relatively thin plates 22 are provided which are provided with openings 23 in their upper edges and upwardly extending notches 24 in their lower edges.

Grooves 26 are rovided on opposite side faces of the strut IE1. These are spaced apart according to the spacing of the plates 22 as desired.

The sides of the notches 24 in the plates 22 are preferably arranged in downwardly diverging relation, as shown in Fig. 4, as are the bottoms of the grooves 26 in the strut, as shown in Fig. 5.

The openings 23 in the plates 20 are such as to readily receive the tube 6 and the bottoms of the grooves 26 are such relative to the notches 24 in plates 22 that when the plates are assembled in the notches of the strut there is a wedging action.

With the tube inserted in the openings 23 of the plates 22 the edges of the plates at the sides of the notches 24 thereof are received in the grooves 26 and as the strut is moved towards the tube 6 the wedging action tends to spread or widen the notches and cause the upper opposite side portions of the plates 22 to move inwardly towards one another so that the tube is firmly gripped in the openings 23.

The member 8 may take any form desired and the strut I!) may be secured to the said member and tube 6 in any desired manner.

The notches 26 may be spaced to provide any desired spacing of the plates 22.

The plates firmly gripping the tube as they do and the grooves of the strut acting on the notches of the plates as described not only insure intimate contact of the parts but provides a strong rigid construction wherein the plates and strut cooperate to reinforce the tube against warping and sagging. Also the plates function for the conduction of heat from the tube while at the same time a free flow of air is facilitated around the tube.

It may be desired to provide a series of openings 30 through the bar, as shown, in Fig. 6. This will reduce the weight of the strut and permit air to pass through the strut which may be considered necessary in some cases.

The parts may be made from various materials but aluminum has been found to be desirable for the practice of the invention,

The invention may be embodied in other specific forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claims are therefore intended to be embraced therein.

What is desired to claim and secure by Letters Patent of the United States is:

1. A burner of the class described comprising in combination, a support member and a tube member extending therefrom closed at its outer end and provided with ports along its upper side,

a strut supported by said members parallel to said tube and below said tube. grooves in opposite side faces of said strut spaced apart in pairs, plates having notches in lower edges the sides of which are received in said grooves and provided with openings in upper edges through which said tube member extends, the sides of said notches of the plates and the bottoms of said grooves being similarly diverging whereby a wedging action thereof causes the upper side portions of the plates to be urged inwardly towards one another so that said tube is firmly gripped in the openings of the plates.

2. A burner of the class described comprising in combination, a support member, a tube member extending horizontally therefrom and provided with ports, a strut spaced below and parallel to said tube member having vertically disposed grooves in opposite faces thereof arranged in spaced pairs therealong, plates having notches in their lower edges and openings in upper edges through which said tube member extends, portions of said plates at the sides of the notches received in said grooves, the bottoms of said grooves of the strut and the sides of the notches of said plates arranged in downwardly diverging relation whereby said strut function with awedging action in the notches of the plates to cause upper side portions thereof to move inwardly towards one another to firmly clamp the tube member in the openings thereof.
